Precautionary statements

HOT MATERIAL during installation! WILL CAUSE THERMAL BURNS to skin and eyes if exposed! Wear protective clothing during installation and demolition. Eye Contact: Eye contact with HMA fumes can cause moderate eye irritation, redness, and itching. Airborne dust may cause immediate or delayed irritation or inflammation. Eye exposures require immediate first aid to prevent damage to the eye. Skin Contact: Repeated or prolonged contact to HMA may cause dry skin, discomfort, irritation, and dermatitis. Inhalation (acute): Hot HMA produces irritating fumes or vapors such as smoke, carbon dioxide, carbon monoxide, unburned hydrocarbons. Hydrogen sulfide and other sulfur-containing gases can evolve from this product at elevated temperatures. Exposure to fumes or vapors may cause irritation of the nose and throat, and symptoms such as headache, dizziness, loss of coordination, and drowsiness. Cutting, crushing, or grinding hardened asphalt will release dust. Breathing dust may cause nose, throat, or lung irritation, including choking, depending on the degree of exposure. Inhalation (chronic): Risk of injury depends on duration and level of exposure. Silicosis: This product contains trace amounts of crystalline silica. Under normal use and application, HMA does not release crystalline silica. However; cutting, crushing, or grinding hardened asphalt or other crystalline silica-bearing materials will release respirable crystalline silica. Prolonged or repeated inhalation of respirable crystalline silica from this product can cause silicosis, a serious disabling and fatal lung disease. Carcinogenicity: HMA is not listed as a carcinogen by IARC or NTP; however, HMA contain trace amounts of crystalline silica and benzene that is classified by IARC and NTP as a known human carcinogen. Ingestion: Do not chew or ingest HMA. Ingestion may result in nausea, vomiting, diarrhea, and restlessness. Chewing asphalt has caused gastrointestinal effects. Stomach obstructions have been reported in individuals who have chewed and swallowed asphalt. Aggravated by Exposure: Individuals with preexisting skin conditions can be aggravated by exposure.
